8051 and RGB LED example

In this example we connect an RGB LED to our 8051. In this case we used an RGB LED breakout, this was a common anode device. The schematic below shows the connection to the RGB LED breakout.

We will switch on the main colours individually in the example

Code

The code was written using mikro C PRO for 8051

void main()
{
do
{
P2 = 0xFF; // Turn OFF
Delay_ms(1000); // 1 second delay
P2 = 0xFE;
Delay_ms(1000);
P2 = 0xFD;
Delay_ms(1000);
P2 = 0xFB;
Delay_ms(1000);
P2 = 0xF8;
Delay_ms(1000);
P2 = 0xFF; // Turn OFF diodes on PORT2
Delay_ms(1000); // 1 second delay

} while(1); // Endless loop
}
